Answer:

(7n-2p)(7n−2p) + (2n+4q)(2n+4q) + (q-5p)(q−5p) OR

53n² +29p² +17q² -14np +8nq -10pq

Step-by-step explanation:

The perimeter is found by adding all the side lengths.

P = (7n-2p)(7n−2p) + (2n+4q)(2n+4q) + (q-5p)(q−5p)

We know that (a+b)(a+b) = (a+b)², and (a-b)(a-b) = (a-b)²

P = (7n-2p)² + (2n+4q)² +  (q-5p)²

We know that (a+b)² = a²+b²+2ab, and (a-b)² = a²+b²-2ab

P = 49n² + 4p² - 14np +4n² +16q² + 8nq +q²+25p² -10pq

Recall that density = mass / volume.

Let's plug our known values into the equation.

15 g/cm^3 = 360g / volume

First, let's multiply both sides by volume

Volume * 15 g/cm^3 = 360g

Divide both sides by 15 g/cm^3

Volume = 24 cm^3

Density is defined as the mass per unit of volume. The volume of the ball is 24 cm³.

Density is defined as the mass per unit of volume. It is given by the formula,

Density = Mass / Volume

Given that You have a lead ball with a mass of 360 g. The density of lead is 15 g/cm³.

Now, since density is the ratio of mass and volume. Therefore, we can write the volume of the ball as,

Density = Mass / Volume

Volume = Mass / Density

Volume of the ball = 360g / 15g/cm³

                               = 24 cm³

Hence, the volume of the ball is 24 cm³.

Answer:

r=7

Step-by-step explanation:

C is at x=1 at circle side is at 8

8-1= 7

so, r=7

Answer:

The radius of the circle is 7 units.

Step-by-step explanation:

Radius is the measure from the center point of a circle to a point on the outside edge. Since you have coordinates, you can find the radius using distance formula.

You could also just count how many units are between the center and the edge to get 7 units because 8 - 1 = 7

9514 1404 393

Answer:

  857.4 ohms

Step-by-step explanation:

The new frequency is 50.2/61.4 times the old frequency. Since the reactance varies inversely with frequency, the new reactance will be 61.4/50.2 times the old reactance:

  reactance at lower frequency = (701 ohms)×61.4/50.2 ≈ 857.4 ohms

Answer:

$315. 9% of 875 is 78.75. 9% x 4 years = 36%. 36% of 875= 315. (bonus: 875 + 315 = 1,190.)

Answer: -1/6

Step-by-step explanation: Start by changing the minus a negative

to plus a positive, so we have -2/3 + 1/2.

Since our denominators of 3 and 2 have no factors in common,

our least common denominator is 3 · 2 or 6.

In order to get a denominator of 6 in each fraction,

we multiply top  and bottom of the first fraction by 2

and top and bottom of the second fraction by 3.

That gives us -4/6 + 3/6 which simplifies to -1/6.
